Why can't Urumqi see the stars?

Urumqi can't see the stars for several reasons:

1, light pollution: Urumqi is a densely populated and rapidly developing city with bright lights at night, causing a lot of light pollution. Light pollution will make the sky too bright and block the light of the stars, making it difficult to observe the stars.

2. Air pollution: Urumqi has air pollution problems. For example, particles and dust in the air will scatter and absorb starlight, causing the stars to become blurred or invisible.

3. Weather conditions: Weather conditions will also have an impact on the observed stars. There are often clouds, smog, sandstorms and other weather conditions in Urumqi, which will hinder the observation of stars.

4. Geographical location: The geographical location of Urumqi will also have a certain impact on stargazing. Factors such as geographical orientation and topography will affect the number and brightness of visible stars. When observing the starry sky in Urumqi, we can consider suburbs or places far away from urban areas to reduce the influence of light pollution and air pollution on observation. At the same time, choosing a sunny period, such as a partly cloudy or cloudless night, can increase the possibility of observing stars.
